Combustion pressure measurement is very challenging in the aggressive application of 2-stroke engines. The unique and reliable Cylmate pressure transducer has proven its maintenance- and calibration-free performance during years of continuous operation.
Transducers have been installed for over a decade, and still in operation providing us user experiences from thousands of installed pressure transducers.
The measuring accuracy is not influenced by any clogging or heat flash from the combustion gases, which potentially could be a problem with other pressure transducers. Cylmate pressure transducers do not have any aging phenomena and is not affected by pressure cycling, temperature cycling, combustion gases or combustion residues. Therefore, the Cylmate pressure transducers do not need any recalibration. The transducers critical parts are made of Inconel.
According to the magneto-elastic effect, the magnetic properties of a ferro-magnetic material are influenced by the mechanical forces acting on it. A typical transducer has four holes with two windings passing at right angles to each other. One of these serves as the primary winding and the other one as the secondary winding. No coupling exists between the two windings as long as there is no load acting on the transducer. If a mechanical force is applied to the transducer, the permeability of the material in terms of magnetic flux is changed in such a way that a voltage is induced in the secondary winding. The induced voltage is proportional to the applied pressure.
